Sadly late 2021 the original dev passed away. Someone has taken over stewardship of the project but it is currently moving slowly and they are seeking more contributors (javascript skills are a plus).
He was a bit of a hn user and seemed good natured and pleasant. Though I didn't know him I was sad to hear he'd passed both as a Redirector user and a fan of good people doing good things. I know he'd mentioned being happy to get recognition on here. https://news.ycombinator.com/user?id=einaregilsson
I really enjoyed the original devs write up on creating an easter egg specifically targeting Mark Hamills avatar in game. https://einaregilsson.com/an-easter-egg-for-one-user-luke-sk... https://news.ycombinator.com/item?id=30715746
Oups linked the wrong hn thread about that easter egg. Here is the one that got a bunch of attention back in 2017: https://news.ycombinator.com/item?id=14653017
for firefox, i use `request-interceptor` ( https://addons.mozilla.org/en-US/firefox/addon/request-inter... )
though sadly it has not had an update in a while (a dark mode would be great) (and rarely, a page-url match does not always match a request-rule where i believe some javahell shinanigans take over and somehow get their way)
Really sad to hear.-
